BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a bed sheet assembly, and more particularly to a bed sheet assembly that is easily and conveniently connected to and disconnected from a mattress.

2. Description of Related Art

In a hotel, service personnel of the hotel are often seen making beds by attaching a bed sheet to a mattress, covering the bed sheet with a flat sheet, placing a blanket or a comforter on top of the flat sheet and subsequently placing a bed cover on top of the blanket/comforter. Bottoms and sides of the bed sheet and the flat sheet are tucked under the mattress so as to form a pouch between the bed sheet and the flat sheet. Thereafter, when a user is sleeping in the pouch formed by the bed sheet and the flat sheet, the pouch is able to keep the user at the required temperature and thus the user should be kept warm all through the long night. However, no matter in what kind of position the user sleeps, the user never remains in the same initial position. That is, sleepers inevitably roll over and over again during sleep. The bottoms and the sides of the bed sheet and/or the flat sheet may thus be pulled out from underneath the mattress. As a consequence, the user may easily come down with a cold or at least suffer disrupted sleep.

In addition, the hotel personnel always exchanges used the bed sheet and flat sheet for new ones but does not change the blanket or the comforter, such that sanitary problems may occur when many persons have used a same blanket or comforter.

Furthermore, when the bed is prepared by a single person, the work and time for preparing the conventional bed sheet assembly is tremendous and troublesome.

To overcome the shortcomings, the present invention tends to provide a bed sheet assembly to mitigate the aforementioned problems.

SUMMARY OF THE INVENTION

The primary objective of the present invention is to provide a bed sheet assembly that is conveniently assembled or disassembled and is easily connected to and disconnected from a mattress. The bed sheet assembly has a bed sheet and a pad cover. The pad cover is detachably connected to the bed sheet with a first connection device and adapted to detachably mount on and enclose a mattress.
